Specification of Letters Patent. Patented Apr. 22, 11919.

Application filed March 3, 1919. Serial No. 280,249.

To all whom it may concern.-

Be it known that I, LEONARD A. YOUNG, a resident of the city of Detroit, county of Wayne, and State of Michigan have invented certain new and useful Improvements in Upholstery Back-Spring Construction, of which the following is a specification.

It is frequently desirable in back spring construction to provide an extremely yielding spring that will at the same time carry the upper edge portion'or roll part of the upholstery so that it does not break down while it will yield to sidewise pressure quickly and resist application of weight from above.

This invention relates to back spring construction in which a very resilient arch is had that yields readily without permanent deformation either under lateral or down ward pressure, and is arranged to provide adequate support to the upholstery so that the latter does not sag.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in vertical section of an upholstery spring construction embodying features of the invention; and

Fig. 2 is a view in detail of one form of back arch that may be used in the construct1on.

As herein shown in preferred form, the back panel or frame 1 of the seat has the usual upper rail 2 Arches 3, of which one only is shown, formed in any suitable mannor, are each articulated as by links 4 to the lower portions of the frame and are held in spaced relation therefrom yieldingly by body springs 5.

In preferred form each arch 3 is made of a wire or strip of resilient material bent between its ends to provide substantially parallel spaced arms integrally connected at the downturned upper end portions 7 by an off set cross -member 8, the lower end piece 9 overlapping and being secured together as by-the links 4.

The angles or corners 10 at the abutment, or if the abutment is ofiset oppositely to the direction indicated, the portion 8 itself, form bearing places on which the arches rock when the body springs 5 are compressed under load suliiciently to cause the arches to contact at these places with the back frame.

Upholstery consisting of a lining 12, the usual filling material 13 and a cover 14-, is placed on the arches. The flexible fabric of the lining 12 and if desired, of the outer covering 14, are attached as by tacks 15 or the like, to the rail 2 of the back 1 so that the arches are restrained somewhat or limited in outward movement caused by the back springs 5 which tend to project the arches from the frame.

In operation, any load directed against the bodies of the arches, sufficient to compress the body springs to a point where the abutments rest against the back, causes the arches and springs to flatten toward the back, the arches tilting freely at the upper ends on the abutments and carrying the upholstering above the frame, the arches being disposed preferably so that the crowns or other portions thereof lie above the plane of the upper edge of the back.

If the arches do not contact and are in the position indicated in Fig. 1, a very pliable support is afforded to the rolled edge of the upholstery back itself, the arches yielding freely to load and recovering as readily. If the abutments are in contact, the arches yield readily as the abutments can move up and down on the back frame while there is no possibility of the upper rolled edge portion of the upholstery sagging or otherwise permanently deforming.

Obviously changes in the details of construction may be made without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

As herein shown in preferred form, the back panel or frame 1 of the seat has the usual upper rail 2. Arches 3, of which one only is shown, formed in any suitable manher, are each articulated as by links 4 to the lower portions of the frame and are held in spaced relation therefrom yielding by body springs 5.

In preferred form each arch 3 is made of a wire or strip of resilient material bent between its ends to provide substantially parallel spaced arms integrally connected at the downturned upper end portions 7 by an offset cross member 8, the lower end piece 9 overlapping and being; secured together as by the links 4.

What I claim is:

1. In back spring construction, a back, upright arches connected to the back at upper portions of the arches on which the arches rock when the abutments contact with the back, flexible upholstered fabric on the arches attached to the back and adapted to limit the outward movement of the arches and body springs normally holding the arches in spaced relation to the back.

2. In back spring construction, a back, an upright arch normally held by body springs in spaced relation to the back and provided with an upper crowned portion terminating below the top in abutment portions, a flexible fabric covering the'arch and attaching to the back, the fabric limiting the outward movement of the arch induced by the body springs, and the abutments forming a rocking bearing for the arch against the back when a load compresses the body springs suhiciently.

3. In back spring construction, a back,

"an upright arch normally held by body springs in spaced relation to theback and provided w1th a crowned upper portion havin the bends thereof above the lane of c n I the upper edge of the back and terminatmg 'below the plane of the upper edge of the backin abutments, and upholstery applied tothe arch including a flexible fabric bridging the space between the crown of the arch and the back and attaching to the back, the

fabric limiting the outward movement of the arch induced by the body springs and the abutments forming rocking bearings for the arch when a load compresses the body springs sufficiently.

4. In back spring construction, upright arches each consisting of a wire or strip of resilient material bent to form. a pair of substantially parallel spaced arms having crowned upper portions with depending end portions that form abutments adapted to contact with the back, body springs holding the arches normally in spaced relation to the back and a flexible fabric over the arches attached to the upper portions of the back and limiting the outward movement of the arches under the efi'ect of the body springs, the abutments forming rocking bearings for the arches when the load compresses the body springs sufficiently.

5. In back spring construction, a back, upright arches provided with abutments dependant from inrolled and crowned upper portions of the arches, on which the arches rock when the abutments contact with the back, means articulating the lower end portions of the arches to the back upholstery on the springs and flexible means forming portions of the upholstery .and attaching to the upper portion of the back, adapted to limit the outward movement of the arches under the effect of the body springs.

6. In back spring construction, arches each consisting of a resilient wire or-strip bent between its ends to form spaced, substantially parallel arms -with crowned upper portions having depending abutments, the other end portions of the arms being connected, members articulating the lower end portions of the arches to the back body springs interposed between each arch and the back and adapted to normally project the arches from the back with the abutments at an interval therefrom and upholstery applied on the arches including a sheet of flexible fabric spanning the normal gap between the arches and the back and attaching to the back, the fabric limiting the outward movement of the arches under the influence of the body springs.
